Github (rz195440) MCP Server
@rz195440/server-github-mcp
npm
v0.0.1
Published by @rz195440 — no publish provenance, so origin is unverified, but the source is public: the repository link below is self-declared yet readable, so you can inspect the code before adopting it.
MCP server for using the GitHub API
The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.
1. Threat score — 100 − 3.6 = 96. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −3.6 | Possible combosquat of @modelcontextprotocol/server-github MTC-SUP-006 | supply-chain |
2. Client adoption risk — 96 − 7 = 89. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:
| Points | Adoption-risk factor |
|---|---|
| −6 | capability blast radius (high) — client exposure if the model is manipulated |
| −1 | publisher verification (public source) — no provenance, but the source is public and inspectable |
Capability observations and info notes are shown under Findings but never scored.

Findings 2
high Sensitive-source and external-sink co-existMTC-FLOW-004
Tools that read sensitive data ([get_file_contents]) and tools that can send data out ([create_issue, create_pull_request, create_pull_request_review]) are exposed together. An agent can move private data to the sink.
Evidence: sources [get_file_contents] → sinks [create_issue, create_pull_request, create_pull_request_review]
Fix: Keep secret-reading and egress capabilities on separate, separately-approved servers.
Location: flow get_file_contents → create_issue
medium Possible combosquat of @modelcontextprotocol/server-githubMTC-SUP-006
"@rz195440/server-github-mcp" is "@modelcontextprotocol/server-github" with a decorative suffix — a common combosquat pattern.
Fix: Confirm you meant "@modelcontextprotocol/server-github". Install packages only from their documented, official name.

Toxic flows 1
Cross-tool combinations that form a data-exfiltration primitive (untrusted input → sensitive source → external sink).
What this scan could not see
- Tools were statically extracted from the published source (28 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Versions 1
Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.
| Version | Score | Findings | Engine | Scanned |
|---|---|---|---|---|
v0.0.1 latest |
B 89/100 | 2 | 1.13.0 | 2026-09-07 |
Embed this score
Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
Verify this score yourself
The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
